so ive looked around for tunners for my truck and i think there all pretty much bs. what would i have to get for my laptop and truck for me to be able to tune it. would a van ecu make a diff in a truck like the ambulance ecus do in the diesels. any advice or comments help thanks

 

There is no easy power with a non-turbo motor, so tuners aren't much use until you add enough performance parts to exceed the capacity of the stock fuel system.

 

oh alright what about the timing on a pretty much stock motor just has a k&n, headers with full exhuast

 

Advancing the timing is easy with a timing gun, just pull the spout plug and rotate the distributor. Results vary with use and the condition of the motor and EFI system, but on average the truck motors will tolerate 2-4 degrees additional advance, and more with higher octane fuel. Stock base timing is 10deg advance.
